Yami Law: A. Data Format Requirement
OBJ Data Format（required ）B. Parameter Setting & Operation Steps Upon completion of Aerotriangulation, Reconstruction menu will be generated, you could select "No tiling" (small project）or "Regular Planar Grid"（large project）as Tiling Mode in the Spatial framework tab. Currently, ”Regular volumetric grid” or ”Adaptive tiling” is not well supported.
Note: the coordinate parameter here in the "Spatial reference system" must be the same as that is selected in B.3.
Clicking Submit new production, "OBJ wavefront format" should be selected as Format in the Format/Options tab, tick "include texture maps", leave "Level of detail" unchecked. Select "Tile Overlap" and keep its default value (which will be auto-computed from the system, it is not suggested to set into 0.049 meter as pictured). Other options setting can be adjusted according to the user needs.
Click Next and come to Spatial reference system tab. Note: the coordinate parameter here in the Spatial reference system must be the same as that is selected in B.1. Otherwise, the final model will not display in normal mode.(In addition, "China Geodetic Coordinate System 2000 - China 2000 (EPGS:4490)" should not be selected. You must choose the relative coordinate system with the origin.)
If the aerotriangulation files and photos after distortion correction need to be imported, please follow the steps as below: click a Block_AT on the left panel, select Block->Export->Exprt to XML in the menu bar, choose "BlocksExchange XML format" as Output format and "Rotation matrix" as Rotation format, finally check Export photos without lens distortion.
Note: the coordinate system outlined in the red box needs to be the same as those selected in B.1 and B.3 in order to keep the same coordinate systems between the camera and obj.Finally, double check the export result： The result should be packages of Tile_+X_+Y folders，each folder represents a Tile, including a obj model, mtl material file and relevant texture file. Please use Meshlab to open the obj model so that it can display normally.
Select Render->Show Box Corners from the Meshlab menu. Make sure each Tile is a rectangle (rectangle or square), the model edges are aligned to the XY axis, and the Z axis corresponds to the elevation. Meanwhile, you can use the buttons in the menu icon to measure the coordinates of model's four corner points. The X or Y value of the corner point should correspond to the Min or Max value in the Bounding Box.
C．Upload to altizure.com
Compress the obj model and metadata file into .zip package and upload to altizure.com.
Zip file#1 & #2 into file#3 and upload it to altizure.com
Click Create, select Third-party Model and click Photogrammetric Model.
Upon completion of the conversion, your context capture results can be viewed on the Internet without any restrictions. Besides, you could put the model on the [Planets] (https://planets.altizure.com) for more creation and application.D. FAQ
What to do when the zip archive is too large to upload, or the conversion process prompts "zip file error"?
A: You can use the 7zip or other tools to perform volume compression. Divide a large compression package into files of about 200 Mbyte each and then upload all these files to the project.
When the context capture model is uploaded for conversion, many cracks appear as the following figure. How to solve it?
A: This problem is caused by inconsistencies in the coordinate systems selected in steps B.1 and B.3. The coordinate systems selected in B.1 and B.3 must be the same to avoid such cracks.
How to assign the geographical coordinates?
A: Adding a metadata.xml file to the archive file with coordinate information description. Usually the metadata file is placed at the root of the archive directory and its file format is as below.
A: You need to manually enter the center coordinates (SRSOrigin) of the xml into the "local translate" in the final_report.json file.

Download and run DJI Simulator on Windows
Click to download and install DJI PC Simulator and Windows Driver. (Note: they are official DJI Simulator installers, but DJI has removed those download links from their website)
Open DJI PC Simulator and click Display Simulator
Connect your aircraft to computer
Power on your aircraft with propellers detached.
Use a USB cable to connect your aircraft and computer.
The SN section in simulator should show the SN of your aircraft. If the SN is empty, you may need to reconnected the USB cable or reinstall the driver.
Enter the Latitude and Longitude near you, then click Start Simulation. Once connected, the button should be greyed out, latitude and longitude are shown in simulator.
In simulator, you can control your aircraft using your remote controller, DJI Go, Altizure and any other third-party DJI app, This will help you learn how to use these app without danger.
Try Altizure app
Connect your remote controller with Altizure app.
Find aircraft's location at simulated location, and start a new mission.
Here is DJI's guide on using the simulator.
Your aircraft takes photos in simulator, too. So you may need to delete these photos to free up spaced in SD card.
Scroll your mouse wheels to zoom in/out in simulator.
Right click the simulator, select setup, tick show trace, then you can see the flight path.
